Change GIF Speed
Speed up or slow down an animated GIF by changing frame delays without dropping frames.
Change GIF Speed uses a separate frame-aware pipeline; it never sends an animated file through the static first-frame canvas path.
How OpenFileTools processes it
Local processing, explicit choices.
The browser lazy-loads GIF decoding and encoding code, composites disposal-aware frames, applies the operation to every frame, and creates an animated GIF locally.

| Timing | All delays scaled and safely clamped |
Change delays without dropping frames
Preset or custom speed divides every frame delay while retaining frame order and count. Very short results are clamped to the minimum reliable GIF delay.
- Custom speed accepts 0.05× through 20×.
- Original and new duration are shown before processing.
